But i have a suggestion on this.As u basically want to allocate each of ur isp a specific max-bandwidth they can pull, so it would be better if u use MQC with policing applied for better throughput and interface congestion control to avoid drops as with CAR rate limit , lot of drops do occur once the other end is trying to reach the threshold.

But neverthless u can go ahead with ur plan.

Hope this helps u .

Please do rate the post as it would help us to give valuable output useful to all.

Re: Car config example ??????

Hii..

thnks for accepting the answer.

yes the encapsulation has to be used on every subinterface u create for a particular isp(in ur case) , as u r using logically created interfaces for the traffic flow.This would mean the flow frm each isp wud be having a dotiq tag with it to differentiate it frm other isp flow.The tag wud identify flow and de-tag once it passes of thru the trunk to one of the other core devices..say for eg.backbone/gateway router interface.

AS for MQC ..

int gig 0/1

no ip address

speed , duplex settings..

int gig /1.101

encapsulation dot1q

ip address 192.168.65.1 255.255.255.252

service-policy input test1

service-policy input test2

define the policy maps.

class-map movingout

match access-group 150

class-map movingin

match access-group 151

Policy-map test1

class movingin

police 2048000 128000 conform-action transmit

Policy-map test2

class movingout

police 1024000 64000 conform-action transmit exceed-action drop

these are modular class maps attached to policy maps,which define the flow to be considered and then given to policy maps for action .
